DJango how to create path to custom method in view?
I've been learning django for a few days and I started creating a simple project. However I have small problem with urls. In my project I created view: views/cars/scrapped_view.py from app.models import ScrappedCar from django.views.decorators.csrf import csrf_exempt from django.utils.decorators import method_decorator from rest_framework import status from rest_framework.views import APIView from rest_framework.response import Response from rest_framework.request import Request @method_decorator(csrf_exempt, name='dispatch') class ScrappedView(APIView): def get(self, request: Request) -> Response: # /cars/scrapped scrapped_cars = ScrappedCar.objects.all() return Response(scrapped_cars, status=status.HTTP_200_OK) def related(self, request: Request, id=None) -> Response: # /cars/scrapped/<int:id>/related scrapped_car = ScrappedCar.objects.get(id=id) related_scrapped_cars = ScrappedCar.objects.filter(user_id=scrapped_car.user_id, paid=True) return Response(related_scrapped_cars, status=status.HTTP_200_OK) The problem is that I don't know how to create a path to the method related. I was trying many different things but nothing works. Here you can see few of them: urls.py from django.urls import path from .views.cars.scraped_view import ScrapedView urlpatterns = [ path(route=‘cars/scrapped’, view= ScrapedView.as_view()), # works # path(route='cars/scrapped/<int:id>/related', view=NegativeKeywordView.as_view()) not working # path(route='cars/scrapped/<int:id>/related', view=NegativeKeywordView.as_view({‘get’ : ‘related})) not working # path(route='cars/scrapped/<int:id>/related', view=NegativeKeywordView.related) not working ] Do you know what I am doing wrong? How I can create path /cars/scrapped/<id>/related to the method related? -
Django - Find sum and count of values in child table using serializers
I have two tables: Event and EventTicket. I have to return total transactions and total tickets sold of each event. I am trying to achieve this using Django serializers. Using only serializers, I need to find the following: 1. total tickets sold: count of items in EventTicket table for each event 2. total transactions: sum of total_amount of items in EventTicket table for each event where payment_status: 1 I read about SerializerMethodField but couldn't find a solution specific to this scenario. class Event(models.Model): name = models.CharField(max_length=100, null=False, blank=False) description = models.TextField(null=False, blank=False) date_time = models.DateTimeField() class EventTicket(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE) event = models.ForeignKey(Event,on_delete=models.CASCADE) payment_status = models.SmallIntegerField(default=0, null=False, blank=False) ## payment_success: 1, payment_failed: 0 total_amount = models.FloatField() date_time = models.DateTimeField() My desired output is: "ticket_details": [ { "event_id": 1, "event_name": Event-1, "total_transactions": 10000, ## Sum of all ticket amounts of event_id: 1, where payment_status: 1 "total_tickets": 24, ## Count of all tickets that belong to event_id: 1 }, { "event_id": 2, "event_name": Event-2, "total_transactions": 10000, ## Sum of all ticket amounts of event_id: 2, where payment_status: 1 "total_tickets": 24, ## Count of all tickets that belong to event_id: 2 }] -
Partial change in the model of one field for individual users - DRF

How I see it: url - for view Check_status And view Check_status class CheckStatusView(generics.RetrieveUpdateAPIView): queryset = Task.objects.all() serializer_class = TaskDetailSerializer permission_classes = [permissions.IsAuthenticated] and then I think I need redefine this def put(self, request, *args, **kwargs): return self.update(request, *args, **kwargs) or def patch(self, request, *args, **kwargs): return self.partial_update(request, *args, **kwargs) or maybe: def partial_update(self, request, *args, **kwargs): kwargs['partial'] = True return self.update(request, *args, **kwargs) I want the user/users who will in field assigned_to the Task to only be able to edit the field Status. -

How can I customize text wrapping and text style in Bokeh table?
I have a base Bokeh table in Django Python. I have it displayed in its basic form - as by default without any style editing. At me all words are superimposed on other columns of the data. What's in the header of the table - what's in the body of the table. I can not change the font of the table - the title and body of the table. How can I set up a data-wrapped display of table text on another line? And how can I change the font of the text inside the table - the table header and table body? My table does not expand to the entire DIV container in which it is located. Sometimes layering on other template objects. How can this be set up? def table_htmx(request): context = {} qs_select_tabl = Table_model.objects.filter(name_1=select_1).order_by('name_name') qs = qs_select_tabl.values() df = pd.DataFrame.from_records(qs) header = [field.verbose_name for field in Table_model._meta.get_fields()] df.columns = header template = """ <div style="font-size: 100%"> <%= value %> </div> """ template_html = HTMLTemplateFormatter(template=template) columns = [TableColumn(field=col, title=col, formatter=template_html) for col in header] source = ColumnDataSource(df) data_table = DataTable(source=source, columns=columns, width=800) script, div = components(data_table) context['script'] = script context['div'] = div return render(request, "table_htmx.html", context) -

I know that it is possible to output them through TabularInline . And it seems that there is a read-only property here. Maybe there is a way to display just a list in a column or row separated by commas? Now, I have this code in admin.py: @admin.register(Refbook) class RefbookAdmin(admin.ModelAdmin): list_display = ['id', 'code', 'name'] I tried to create a "get_versions(self)" method in models.py in Refbook class, in which I received a queryset using related_name. But I can't display it in the admin panel. Or is it still correct to do this using the model.ModelAdmin parameters? -
How to ensure consistency between Django models and underlying databases
On our staging server we observed a runtime error stating a field is missing from a database, column our_table.our_field does not exist LINE 1: ...d"."type", "our_table"... The field was added in a latest update during some complex migration squashing process, through which we should have made some mistakes. Since manage.py showmigration did show the migration has been applied and we do not run our tests on staging/production servers, we are wondering what is the best way to detect such an error. To rephrase the question using a simpler example, how to detect inconsistency between database structure and Django models after an incorrect migration introduced by something like the following? python manage.py migrate our_app --fake I suppose I am looking for something like python manage.py check_database -

How to print elements of list of an unknown number of zipped lists in Djanto templates
a = [1,2,3,4,5] b = [[3,4],[4,5],[6,7]] out = [[x if x in l else 'X' for x in a] for l in map(set, b)] z = zip(a,*out) In above code the list a will have fix number of elements but list b will be varying, hence elements in z will vary as well. Now in Django template I would Like to print the elements of z. What I tried for above scenario is {% for d,s1,s2,s3 in z %} <tr> <td> {{d}} </td> <td> {{s1}} </td> <td> {{s2}} </td> <td> {{s3}} </td> </tr> {% endfor %} Which works fine if I know the number of elements present in the z; but unfortunately it's varying. Sometimes it could have 10 lists , sometimes nothing. Sometimes the scenario will be like below: {% for d,s1 in z %} <tr> <td> {{d}} </td> <td> {{s1}} </td> </tr> {% endfor %} So How can I correct above template code to print variable number of list elements in the table? Thanks. -

How can two HTML template elements be updated using (HTMX)?
I have a form in which there are three fields, basically these fields contain drop-down lists - selections. These select lists are based on a data model that has fields associated with ForeynKey . After completing this form. I update information, code and do calculations in code. Further after the calculations. I am updating two elements on the template - a table and a graph. I have these two elements in separate parts of the template. Like two different pieces of HTML .

Using stripe.js with dj-stripe
I'm using django and I want to integrate stripe using the abstraction layer dj-stripe. From what I understand from the documentation, ElementJs with Payment Intent is the preferred way to allow users to enter their payment details. see https://dj-stripe.dev/stripe_elements_js/ However, there is no documentation on how to connect dj-stripe with stripe.js. The first step of the usage documentation in dj-stripe already assumes payment methods have been connected (https://dj-stripe.dev/usage/subscribing_customers/). I looked through the code of dj-stripe and it seems to have Payment Intent classes, but I can't figure out how to use them. How can I generate a client secret for customers created in dj-stripe that can then be used in stripe.js? (Or if I'm not on the right path, what should I do instead to allow adding payment details to be used in dj-stripe) -

Manually It would be possible to separate the logic into different classes. in one class return xml, and in another json but it needs to be implemented in one function The problem I am facing is how to implement this idea. Explicitly specifying the content type does not help. The XML is returned as a string. response.media_type = "application/xml" doesn't help. I broke my head. I miss something important or get confused in simple things separating logic into different classes works correctly, but … -

I can't use try-except in django
I have problem in try-except The file is views.py function 'noun_check' return nouns of the sentence that I received from contenct.para(=input) If there is no noun in the sentence than function 'noun_check' return error If the error occur, go to except and return(request, 'main/desktop.html'), and receive another sentence. And If I got nouns, I return render(request, 'main/introduction.html', context). This is the way I thought. But error occured in function 'noun_check', logic doesnt' go to except, and return render(request, 'main/introduction.html', context) Could you explain why try-except doesn't work? def submit(request): if request.method == 'POST' and request.POST['input'] != '': try: content = Diary_content() content.para = request.POST['diary_input'] tokenized_nouns = noun_check(content.para) context = {'para' : content.para, 'emotions':tokenized_nouns} return render(request, 'main/introduction.html', context) except: return render(request, 'main/desktop.html') I seperate the function, and made function if error occur return False And use temp = function(sentence) \n if temp == 0: ... Althogh 'temp == 0' is True, logic doesn't go under 'if function' -
